The driving point impedance of a one-port reactive network is given by Z(s)=5(s^2+4)(s^2+25)/s(s^2+16). After taking the partial fractions, what is the value of L∞?
(a) 2
(b) 3
(c) 4
(d) 5
I had been asked this question during an online exam.
The above asked question is from Synthesis of Reactive One-Ports by Foster’s Method topic in chapter Elements of Realizability and Synthesis of One-Port Networks of Network Theory
